About

Agent Builder is part of OpenAI’s tooling for constructing agentic applications, systems that use large language models to perform multi-step tasks autonomously, with governance, tool integration, memory, orchestration, and observability baked in. The platform offers a composable set of primitives—models, tools, memory/state, guardrails, and workflow orchestration- that developers assemble into agents capable of deciding when to call a tool, when to act, and when to halt and hand off control. OpenAI provides a new Responses API that combines chat capabilities with built-in tool use, along with an Agents SDK (Python, JS/TS) that abstracts the control loop, supports guardrail enforcement (validations on inputs/outputs), handoffs between agents, session management, and tracing of agent executions. Agents can be augmented with built-in tools like web search, file search, or computer use, or custom function-calling tools.

About

Polyant is an open source platform for building teams of specialised AI agents that work alongside the people in a company, handling work like sales briefs, customer triage, document extraction, and compliance reporting. Its composable, self-hosted architecture lets teams choose their own model providers, including open-weight models, and their own infrastructure, so they're never locked into one vendor. Governance and audit tooling designed around EU AI Act requirements is built in from day one, with every agent decision logged in an audit registry compliance teams can query directly. Companies keep full control over data residency, deploying on-premises, in their own cloud, or on EU infrastructure managed by Exelab. And agents reach production in days rather than months, without giving up self-hosting or governance. It's built for mid-to-large European enterprises in regulated sectors like banking, insurance, and healthcare, where "just use a hosted API" isn't an option.
